Donald Trump is the biggest popular-vote loser in history to ever call himself President. In spite of the fact that he has no mandate, he will attempt to use his congressional majority to reshape America in his own racist, authoritarian, and corrupt image. If progressives are going to stop this, we must stand indivisibly opposed to Trump and the Members of Congress (MoCs) who would do his bidding. Together, we have the power to resist — and we have the power to win.We know this because we’ve seen it before. The authors of this guide are former congressional staffers who witnessed the rise of the Tea Party. We saw these activists take on a popular president with a mandate for change and a supermajority in Congress. We saw them organize locally and convince their own MoCs to reject President Obama’s agenda. Their ideas were wrong, cruel, and tinged with racism— and they won.We believe that protecting our values, our neighbors, and ourselves will require mounting a similar resistance to the Trump agenda — but a resistance built on the values of inclusion, tolerance, and fairness. Trump is not popular. He does not have a mandate. He does not have large congressional majorities. If a small minority in the Tea Party could stop President Obama, then we the majority can stop a petty tyrant named Trump.To this end, the following chapters offer a step-by-step guide for individuals, groups, and organizations looking to replicate the Tea Party’s success in getting Congress to listen to a small, vocal, dedicated group of constituents. The guide is intended to be equally useful for stiffening Democratic spines and weakening pro-Trump Republican resolve.We believe that the next four years depend on Americans across the country standing indivisible against the Trump agenda. We believe that buying into false promises or accepting partial concessions will only further empower Trump to victimize us and our neighbors. We hope that this guide will provide those who share that belief with useful tools to make Congress listen.
